Following the completion of the presentations, these will be uploaded on to the CHEERS project website as part of knowledge dissemination.

CCS in the US has over the past decade or so been primarily linked to enhanced oil recovery (EOR) as its main driver. The recently passed Bipartisan Budget Act of 2018, however, includes a number of changes to the tax provisions which could prove to be a significant game changer for CCS developments in the US, by providing high-enough incentives for investments into CO₂ capture and permanent storage.

Lack of financial incentives for permanent storage of CO₂ has been one of the main inhibitants for CCS developments, in the US and elsewhere around the world. This has resulted in enhanced oil recovery (EOR) being the main driver for CCS developments in the US. The inclusion of the bill on Furthering carbon capture, Utilization, Technology, Underground storage, and Reduced Emissions Act (FUTURE Act) in the recently passed Bipartisan Budget Act of 2018 (hereinafter referred to as the Act), however, could result in an increased shift towards CO₂ capture for permanent storage.

The changes

Essentially, the new Section 45Q, within the Act, increases the amount of the credit received, the time window for carbon capture projects, and the number of years to claim the credits. Before the passage of the Act, Section 45Q provided a $10 credit for each tonne of CO₂ either used for EOR or other use, and $20 credit for permanent storage. The changes now provide for a tax credit, starting at $12.83 (for EOR) and $22.66 (for permanent storage) per tonne of CO₂ in 2018, which is set to increase in a linear fashion to $35 and $50 per tonne of CO₂ by end of 2026 respectively. After 2026, these amounts would be multiplied by inflation adjustment factor for a particular calendar year. In addition, whereas before, the amount of CO₂ eligible for receiving credits was capped at 75 million tonnes, this has now essentially been removed, as it allows for receiving credits for any qualified facility for up to 12 years beginning on date the equipment is placed in service.

It is worth noting that the applicable new amounts of tax credits refer to the CO₂ captured using equipment which was put in place on or after enactment of the Act. For the CO₂ captured from facilities with CO₂ equipment in place before the enactment of the Act, the old tax credit levels apply. However, in case qualified facilities which have been capturing CO₂ before enactment of the Act install additional capture equipment, the total amount of CO₂ captured is eligible for the higher tax credits. In addition, any facility which captures not less than 500,000 metric tonnes of CO₂ during a year can be deemed, for the purposes of receiving tax credits, as having been in service on the date of the enactment of the Act.

Finally, the eligibility threshold for receiving the said tax credits has now been reduced from 500,000 to 100,000 tonnes of CO₂ captured and stored on an annual basis. This change is particularly important as the higher threshold is believed to have prevented smaller industrial projects from using the tax credit incentives.

The table below shows some of the changes in tax credits brought about the new Act.

Table 1: The pre- and post-Act tax credits for EOR and geologic sequestration

It is worth noting that the captured CO₂ that is eligible for receiving the credits applies to CO₂ captured from power plants, industrial sources and direct air capture facilities. However, the CO₂ used for EOR and natural gas recovery process that is then recaptured, recycled and re-injected as part of these processes is not eligible to receive these credits.

In 2014, 64% of the CO₂ captured from industrial processes (mainly from ethanol, natural gas processing, ammonia production) and 91% of CO₂ produced from natural sources was used for enhanced oil recovery. The remainder of the captured CO₂ is also used in food and beverage manufacturing and/or pulp and paper manufacturing, fire-fighting equipment and metal fabrication. In addition, it is worth noting that in 2014 there was approximately 64 million metric tonnes of CO₂ received for underground injection from close to 100 facilities, of which 63 million metric tonnes was intended for enhanced oil recovery.

Recognising CCS in the context of climate change and energy security have been the main drivers behind the new changes to the tax credit system, receiving wide support on both sides of the political spectrum in the US. In this respect, Senator Shelley Moore Capito (R-WV), notes that these changes will lead to the US becoming a leader in developing and exporting carbon capture systems. Senator Sheldon Whitehouse (D-RI) sees the expansion of 45Q tax credits as “…a big win for our climate and the promising new carbon capture and utilization technologies looking to gain a foothold in the market…[and] a key step forward in combatting climate change by putting a dollar value on reducing carbon pollution.”

In any case, it appears that the changes to the tax credit system described above are expected to provide both an increased certainty and incentive to potential project developers, thereby spurring development of carbon capture and storage in the US. Only time will tell, however, whether the proportion of CO2 intended for storage, as opposed to EOR, will increase.

Concerns remain

The captured CO₂ has in the past, and is likely in the future to be used in EOR for shale oil production. This has raised questions on the implications this would have on the residual CO₂ storage associated with EOR and the integrity of the geological structures. In this respect, the strict monitoring and reporting regulations are envisaged to mitigate the risk of any adverse events occurring.

Chinese-European Emission-Reducing Solutions
(CHEERS) R&D project kicks off

February 6th, 2018

The Chinese-European Emission-Reducing Solutions project (CHEERS) has now received all formal confirmations from the funding agencies. On 28 November, 30 members and representatives of the CHEERS project consortium gathered in Trondheim, Norway, to formally kick off the project. The project will, within five years, look to develop, upscale and test a 2nd generation chemical-looping technology at a scale of 3MW to produce energy and steam with captured CO₂. The aim will be to drastically reduce the efficiency drop of the CO₂ capture chain. The innovative concept is deemed capable of removing 96% of combustion-related CO₂ while eliminating capture losses to less than 4%, except for the CO₂ compression work. Thereby, the project seeks to make a major step towards large-scale carbon footprint reduction of power/steam generation system using heavy feed namely petcoke.

With a budget of €16.8 million, the project is partially financed by the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 764697 together with the Chinese Ministry of Science and Technology (MOST) and Chinese industry. The system prototype demonstration, which is based on a fundamentally new fuel-conversion process, will be carried out at the Key Laboratory for Clean Combustion and Flue Gas Purification of the Sichuan Province, in Deyang, P.R. China.

The responsibility of the action lies with the CHEERS consortium, which comprises nine parties: SINTEF Energy Research (coordinator, Trondheim, Norway), IFP Energies nouvelles (IFPEN) (Lyon, France), Tsinghua University (Beijing, China), SINTEF Industry (Oslo, Norway), Total (France), Dongfang Boiler Group (Zigong, China), Zhejiang University (Hangzhou, China), Politeknika Slaska (Silesian University of Technology) (Gliwice, Poland), and Bellona (Brussels, Belgium).

Bellona’s report shows that a stepwise roll-out of deep decarbonisation infrastructure, in the form of CO₂ transport and CO₂ storage infra­structure, can enable industrial emitters, employment unions and regional government engage constructively in creating a deeply decarbonised industrial base for Europe.

The presence of infrastructure to take CO₂ away from sources and allow commercial disentanglement along the CO₂ capture, transport and storage value chain will significantly reduce the commercial and organisational obstacles for CO₂ capture at industrial sites. CO₂ Market Makers (regional CO₂ transport and storage infrastructure development organisations) are key in enabling the deployment of an effective CO₂ network in order to reduce costs and risks of industrial deep decarbonisation.

Market Makers that enable deep decarbonisation of industry have come to prominence due to slow prog­ress in deploying CO₂ capture, transport and storage in Europe. The concept of planned and strategic devel­opment of CO₂ infrastructure is not new. In 2005, the Bellona Foundation proposed elements of a CO₂ Market Maker to increase CO₂ use on the North Sea. In its November 2014 on Business Models for Commercial CO₂ Transport and Storage, the Zero Emissions Platform (ZEP, the EU Technology Platform for CCS, in which Bellona plays a leading role) picked up that concept of CO₂ Market Makers to progress CO₂ storage deployment in line with European decarbonisation path­ways.

Some key characteristics of Market Makers are that they address many of the structural market failures that retard CCS and the coordination barri­er in them. Through providing a form of central planning Market Makers give certainty to a CO₂ storage developer that CO₂ will be captured and certain­ty to an industrial CO₂ capture. Another characteristic is that they provide a degree of policy certainty to emitters of decarbonisation require­ments and timelines. At the same time they can act if required to preserve useful retiring infrastructure, such as natural gas pipelines scheduled for decommissioning that are suitable for CO₂ transport.

Bellona shaping the necessary EU regulatory framework for CCS deployment

In May 2015, in a meeting with European Commission Vice President Maroš Šefčovič, ZEP and Bellona present­ed this as a recommended way forward for the EU, re­sulting in the Vice President’s request for an ‘Executable Plan’ for enabling CCS in Europe. Bellona led the work with this plan, which was presented to the Commission in the summer of 2015. A follow-up was requested from the Commission that would iden­tify some key strategic industrial regions for which a CO₂ hubs-and-clusters approach would be particularly relevant. There are now encouraging signs that the Market Mak­er and CO₂ hubs and clusters concepts are being picked up by CCS policy makers in various parts of Europe.

Especially encouraging is the recent news that the Norwegian government has approved funding of the FEED studies for three large-scale industrial CO₂ capture projects (for cement, ammonia and waste incineration respectively) along with a shared transport and storage solution for the three. The preferred solution would be a ship terminal on the Norwegian west coast, connect­ed with a pipeline to take CO₂ to offshore storage. This would open for receiving CO₂ from any emission source with access to shipping facilities. It is a solution which could benefit initial CO₂ Market Makers across Europe and as such closely follows the abovementioned 2015 Bellona CO₂ economy recommendations.

CO₂ transport and storage benefit greatly from economies of scale – costs can be reduced quickly through scaling up and sharing of infrastructure between projects.
